1 Claim.

This invention relates to masons implements, and more particularly to an improved masons guide line holder.

The main object of the invention is to provide a novel and improved masons guide line holder which is simple in construction, which is easy to install on a wall being erected, and which securely holds and locks the guide line with which it is employed.

A further object of the invention is to provide an improved masons guide line holder which is inexpensive to manufacture, which is sturdy in construction, and which does not require that any portion thereof be driven into the wall being constructed, and which therefore provides a considerable saving in time in setting up the guide line.

Further objects and advantages of the invention will become apparent from the following description and claim, and from the accompanying drawings, wherein:

Figure 1 is an elevational view of a portion of a wall under construction on which is mounted a guide line supported by improved guide line holders constructed in accordance with the present invention.

Figure 2 is an enlarged cross sectional view taken on the line 2 2 of Figure 1.

Figure 3 is an enlarged perspective detail view showing the main components of the guide line holder of Figures 1 and 2 in separated positions.

Referring to the drawings, II designates a masonry wall under construction and I2 designates a guide line which is employed to establish a reference line for the laying of the masonry units I3 in a straight horizontal line during the course of the construction of the wall. For this purpose, the line is held in horizontal position by employing a pair of guide line holders I4, I4, engaged with the end corners of the masonry wall, as shown in Figure 1, and serving to secure the opposite ends of the guide line I2.

Referring to Figures 2 and 3, each guide line holder I4 comprises an elongated main block member I 5 of generally rectangular shape formed at one end with a transverse shouldered portion I6. Designated at I'I is a bolt member extending slidably through the shouldered portion I6 normal to the plane of the block member I5 and having a nut I8 threadedly engaged thereon. Designated at I9 is a coil spring surrounding the shank of the bolt member I'I and bearing between the nut I8 and the inside surface 20 of the shoulder I6. The opposite end of the bolt member I'I is formed with a conical head 2| which is rigidly secured in a plate member zz disposed parallel to the block member I5, a, portion of the conical head 2I being exposed, as shown in Figure 3. The plate. member 22 is rectangular in shape and is formed at one end with the beveled edge 23, said beveled edge being convergent toward the left end of the block member I5, as viewed in Figure 2. The pin member I1 is formed adjacent the beveled head 2I with a transverse bore 24 and the bore 25 in the block member which receives bolt I? is ccuntersunk at 26 so that the portion of the shank of bolt I1 in which bore 24 is formed may be at times received in the countersunk recess 26. The front surface of the block member I5 is formed with a V-shaped longitudinal, relatively shallow groove 21 adapted to partially receive the guide line I2, said groove 21 being aligned with the recess 26, as shown in Figure 3.

In setting up the guide line I2, one end of the guide line I2 is first inserted through the bore 24 of one of the bolt members I'I', holding the bolt member in an outwardly extended position against the force exerted by the spring I9 associated therewith. After the line has been inserted through said bore 24 and pulled suiently so that a substantial portion thereof is included between the block I5 and the plate member 22, the plate member 22 is released, allowing the spring I9 to expand and drawing the plate member 22 against the block I5. The guide line I2 is seated in the groove 21 and is compressed tightly against block I5 by the plate member 22. At the same time the portion of the guide line in the bore 24 is drawn inwardly into the recess 26,7bending the guide line, as shown in Figure 2, and locking the guide line relative to block I5. The guide line holder I4 at the opposite end of the guide line is similarly engaged with the line in opposing relationship to the first guide line holder and the guide line holders are positioned against the opposite end corners of the wall under construction, the guide line being drawn tight with one or both of the clamping plate members 22 in outwardly held positions until the desired degree of tension is obtained in the guide line, at which time the plate members 22 are released, locking the guide line in taut position with the holders I4, I4 frictionally engaged against the end corners of the wall.

It will be understood that the setting up of the guide line, as described above, is accomplished by two persons, one holding each of the holders I4. The adjustment of the tightness of the'guide line may be accomplished by one of the persons, since it is only necessary to draw the guide line through one of the holders to tighten the line. The shoulders I6 are engaged against the opposite end corners of the wall I I while the remainder of the block elements associated therewith extend along the wall, the line I2 being supported parallel to the Wall and spaced outwardly by the thickness of the main portion of the block members I 5.

To release the guide line I2 it is merely necessary to pull outwardly on one of the plate members 22, whereby the clamping action thereof on the guide line is released, allowing the line to be loosened and allowing the holders to be removed.

While a specic embodiment of an improved masons guide line holder has beenv disclosed in the foregoing description, it will be understood that various modications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as dened by the scope of the appended claim.

What is claimed is: Y v

A guide line holder comprising a base block 4 having a groove extending throughout the length of one side face thereof, a stop carried by the block and projecting outwardly from the side face thereof remote from the groove, said block having an opening extending transversely therethrough and intersecting the groove, a pin extending through the opening in the block for movement transversely relative to the block, a clamp plate carried by the pin for movement therewith adjacent the grooved face of the block, and yielding means carried by the pin and bearing on the block for yieldingly urging the clamp plate into clamping engagement with a guide line lying in the groove.
